Mapping Extended Circumgalactic Lyα Nebulae Around Quasars With J-PAS --  Circum-Galactic Medium (CGM) is the gas surrounding galaxies outside their disksand inside their virial radii. Lyman-alpha (Lyα) emission is one […]

Title : Evolution of embedded protostars studied with submillimeter and near-infrared observations Abstract : Sun-like stars are thought to accrete most of their final mass during the protostellar phase, where […]

The impact of stellar feedback on galaxies Small-scale stellar feedback can impact the large-scale evolution of galaxies by regulating star formation and by driving galactic fountain flows and outflows. Using […]

Title: From cosmic lasagna to space-time spaghetti -- obtaining the least-model-dependent strong gravitational lensing probe   Abstract: Strong gravitational lensing has advanced as a standard probe to map mass densities of […]

Title: Probing Cold Gas around Galaxies through the Mg II Resonance Doublet Abstract: The structure and kinematics of the gas around and in galaxies are crucial for understanding the multiphase flows […]
